In autumn 2007 i've build a new PC - 4GB of RAM - fast Q6600 CPU - fast 8800 GTS 320MB card - plenty of harddisk space on each partition - no overclocking - nothing, that will push the systems to extrem limits (overheating running 3D graphics, burn out or damaging of RAM sticks or whatever problems occuring by those experiments).I've installed Vista Ultimate 64bit - now with prereleased Vista SP1-ReleasCandidate1 - running without problems - even solved problems with certain USB sticks and the use of Ready-Boost (now with a 2GB USB-stick running perfectly).I've plenty of programs installed - games (older up to newest) - video programs - 3D programs - graphic programs - music programs and, and, and - but all regular programs, no experimental, no unofficial, no special programs doing tricky stuff - no programs which suppose to influence parameters to maybe speed up things by tricks or registry changes ... no daemon CD tools or things like that ... Just a clean Vista Ultimate 64bit with all offiicial updates installed - newest graphics drivers 64bit version ...And The Witcher is running without a crash - even playing 10 hours , 15 hours ...Other games are running without problems ...Other programs running without problems ...So i don't believe it's mainly the games fault, if it's not running. There are for sure a few errors, which stay, even on a clean system, but those are minor.So what's the meaning of this ?I had my time, too, experimenting with hardware, with software - and had many problems ... but until now, my new clean system is better running than any PC/Windows version before. Maybe because i have it running, the way it's suppose to be ?There are such a lot of problems i read in this forum - which are for sure related to each individual set system - but for sure a lot of those systems are filled with hardware/software combinations, that aren't healthy working together with each other - for example a lot of the deeper working special software for sure interfere with the base Windows structure, trying to bend the set limits by force - and everyone is asking, that it will take this without any problems ??No wonder, game console players say, their games are running flawlessly, simply because by the fact, that no one CAN influence the hardware/software running there ...And then people wonder, why the new game, they've bought, isn't working ?? I say it's impossible for a PC game developer/programmer, to foresee and program an error prevention routine for each possible PC hardware/software combination in the world ...So from this point of view, Mobidoy got a really, really hard stand, to cope with all the problems thrown at him ... and this is a task, which he never can comply to 100% ... no one can ...
